Are there any temperatures, or weather or atmospheric conditions that make it so tes cannot be used?
Tes is designed to work outside in the elements snow, sleet, rain, etc. It can operate in temperatures from -30F to 115F. When mounted in a closed vehicle or trailer, good ventilation is a must. For temperatures below 60*F, at least 200 sq. inches of ventilation must be available. For temperatures above 60*F, a forced air fan (see operator manual) must be used to prevent overheating in the vehicle or trailer.
